CONSTRUCTION

A) Setting wood jigs, check alignment and determine jigs #1 and #2.

You can add wood stringers between the jigs to make the assembly stronger.

B) Mount the tubes and bars over the jig so you can rivet them together, Check

that tubes follow the twist. (6º)

C) After cutting the tubes to allow fit counterweight at the tip (see page # 50).

D) Remove the pack of tubes and bars from the jig and place the prebend

aluminum skin (page # 47) over the jig, now you can place the pack of tubes

and bars inside the open skin.

E) Close the skin and start riveting the trailing edge, dont forget to include the

inner reinforcement strips between the skins.

F) use soft rivets to hold skins and tubes.

G) Finish root and tip sections, placing reinforcement plates and tip cover.
